APPARATUS FOR CONDENSING SMOKE, FUMES, AND GASES.

SPECIFICATION forming part of Letters Patent No. 700,934, dated May 27,1902.

Application filed February 4:. 1901. Serial No. 46,021. (No model.)

To all whom it may concern.-

Be it known that 1, WILLIAM B. J AOKSON, a citizen of the United Statesof America, residing at Denver, in the county of Arapahoe 5 and State ofColorado, have invented certain new and useful Improvements in Apparatusfor Condensing Smoke, Fumes, and Gases; and I do declare the followingto be a full,clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same, reference being had to the accompanying drawings, and to thefigures of reference marked thereon, which form a part of thisspecifica- I 5 tion.

My invention relates to an apparatus for condensing smoke, gases, andfumes from steam plants, furnaces, ore-roasting furnaces, and smelters,whereby the carbon and solids are separated from the smoke, fumes, andgases and discharged into the sewer or caught in receptacles when it isdesired to save the carbon or recover the values. By the operation of myimproved apparatus most of the 2 5 gases are united with the wateremployed in the condensing operation; but provision is made for theescape of any excess of gases that do not unite with the water.

The invention will now be described in detail, reference being made tothe accompanying drawings, in which is illustrated an embodimentthereof. v

In the drawings, Figure 1 is a vertical longitudinal section of thecondensing tank,

5 shown connected with the smoke-stack of a boiler-furnace, the latterbeing shown in end elevation. Fig. 2 is a section taken on the line soan, Fig. 1, viewed from below.

The same reference characters indicate the '40 same parts in all theviews.

in size, as shown at 9, where it is conical in go shape and is connectedat its smaller extremity with a pipe 9, which passes through an openingformed in the condensing-tank 10.

The pipe 9 protrudes into the tank 10, its discharge extremity beingreduced or contracted. A steam-pipe 12, leading from the boiler, entersthe discharge extremity of the conduit 9, its mouth being directedtoward the pipe 9. This pipe. discharges a jet of steam and creates apartial vacuum, causing the smoke, 6o fumes, and gases to be dischargedthrough the pipe 9 and into the tank with great velocity. I estimatethat with a boiler-pressure ofone hundred pounds the smoke will bedriven into the tank at the rate of seven thousand five hundred feet perminute. On the inside of the tank directly opposite the dischargeextremity of the pipe 9 is mounted a funnel-shaped receiver 13, whoseinclined walls terminate at a shallow receptacle 13, into which thesmoke, fumes, and gases are directed. This receiver is vertically adjustable in the tank, and any suitable means may be employed to effectthis result. As shown in the drawings, a screw 14 is journaled in lugs10-and engages a threaded'opening formed in the closed bottom of thefunnel-shaped receiver. The outer walls of the funnel are provided withbraces 13, whose free extremities slidingly engage the'inner surface ofthe tank and give the receiver the necessary support. In the top of thetank is located a coil 15of perforated pipe, communicating with thewater-supply pipe 16, provided with a valve 17 for regulating thewater-discharge. The water is sprayedfrom the coil15 downwardly into thetank, as indicated by the dotted lines.

The smoke is driven into the tank with such velocity and forcethat itinstantly unites with the water and steam, and the resulting productsfall to the bottom of the tank and are carried off through the openwater-trap 18 into the sewer or to any suitable receptacle in case it isdesired to recover the carbon. 5 The action of the water and steam onthe smoke is both mechanical and chemical. The gases from smelters andore-roasting furnaces will unite with water and may be discharged intothe sewer, or if they contain mineral values the water may be drawn oifinto suitable regeptacles and the values precipitated at wi l.

The top of the tank is provided with an escape-pipe 20 for any excess ofgases which do not unite with the water. The passage through thisescape-pipe is controlled by a weighted valve, whereby the tank isclosed at the top except when the interior pressure is such as to openit for the gas-escape, as aforesaid.

By reason of the velocity of the discharge through the nozzle 9 thesmoke, fumes, and

gases are carried across the tank into the receiver 13, whichtemporarily suspends the said products and gives the water and steam anopportunity to act upon them more effectively, whereby condensation isfacilitated.

It must be understood that the condensingtank may be made of anysuitable material. As shown in the drawings, it is supposed to be metal;but it is evident that any other desirable material may be employed.

Having thus described my invention, what I claim is 1. In an apparatusfor condensing smokes, fumes and gases, the combination'of acondensing-tank, means for introducing water in the form of a spray intothe tank, a conduit leading from the stack and communicating withthecondensing-tank for discharging the products of combustion thereinto,means for introducing a jet of steam into the tank at the dischargeextremityof the said conduit, to give the desired velocity, and meansmounted on the wall of the tank directly opposite the dischargeextremity of said conduit, for temporarily suspending said products inthe tank to facilitate condensation, substantially as described.

2. In an apparatus of the class described, the combination of a tank,means located in its upper portion and connected with a supply source,for discharging water thereinto in the form of spray, a conduit leadingfrom the stack and communicating with the tank, its discharge extremitybeing reduced in size, a steam-pipe entering the smoke-conduit, andarranged to introduce steam into the tank through the dischargeextremity of the smokeconduit, and a receiver mounted in the tankopposite the discharge extremity of the smokeconduit, to facilitatecondensation.

3. The combination of a condensing-tank, means for spraying waterdownwardly from the upper portion of the tank, a smoke-flue entering thetank below the water-spraying means, means for discharging a steam-jetinto the tank through the discharge extremity of the smoke-flue, and anadjustable receiver mounted in the tank opposite the smoke-flueentrance, to facilitate condensation.

4. In a condensing apparatus, the combination of a tank provided with asuitable outlet at its bottom, a perforated pipe located in its upperextremity for spraying water downwardly thereinto, means for dischargingthe products of combustion into the tank under pressure, and afunnel-shaped receiver located opposite the discharge for said productsto facilitate condensation.

In testimony whereof I affix my signature in presence of two witnesses.

WILLIAM B. JACKSON.
